This invention relates to warping apparatus and more particularly to an improved creel and appurtenances thereof.

The object of the invention is to provide an apparatus for eliminating waste time in the warping operation. To this end I employ a reversible creel arranged to present either of its sides as a front side facing the warper and provided with means for guiding the ends from a yarn supply on the front side of said creel to the warper whereby during the beaming on operation, the rear side of the creel is accessible to an operator for replenishing the yarn supply for a subsequent beaming on operation.

The invention contemplates the use of a duplicate set of dismountable reeds for the warper (each set comprising the usual block reed and condensing reed) one set being in active function on the reed carriage of the warper for beaming on the yarns from the front side of the creel, the other set of reeds being temporarily removed from the reed carriage with remnant ends of previously beamed on yarns reeded therethrough and wound around the same for temporary stowage in a position out of the way of the operator and of the yarns being beamed on.

A stowing frame is provided for containing the idle reeds with the yarn remnants reeded therethrough and the reed carriage has a support to receive the stowing frame for convenient assembly with its reeds when the latter are dismounted from the reed carriage. The stowing frame with its reeds rolled up in the reeded yarns is hung above the spools at the rear of the creel where the operator is replacing and tying in new spools during the beaming on of yarns from the front of the creel.

In the drawings which show a preferred embodiment of my invention,

Fig. l is an end elevation of the creel frame and a rear end portion of the reed carriage;

Fig. 2 is a front elevation of said creel frame with the spools removed therefrom (the rear side being a replica of the front);

Figs. 4 and 5 are front and side views respectively. of the condensing reed assembled with its adapter;

Fig. 6 is a group view of the several parts of the reed stowing frame, together with said block reed, condensing reed and condensing reed adapter:

Fig. 7 is a front elevation of the reed stowing frame" assembled in holding relation with said reeds;

Fig. 8 is a sectional view along line 6 8 of Fig. 7;

Fig.- 9 is a plan view at the front end of the 5 reed carriage; and

Figs. 10, 11, 12, and 13 are diagrammatic views showing the progressive steps in stowing away the yarn remnants of a previously beamed on warp preparatory to reversing the creel and con- 10 tinuing the warping from the replenished side of the creel.

Referring more particularly to the drawings, the creel is preferably in the form of an A-shaped frame I as shown in Fig. l with casters 2 swiveled 15 to the base thereof whereby it may be swung around in position to present either of its inclined sides as a front side facing the warper. Each of the inclined sides of said creel are exactly alike and are provided with the usual skewers 3 for receiving spools 4 of yarn. Although I have shown a flanged form of spool rotatably mounted on said skewers I wish the term spool as herein used be understood as any form of yarn supply element from which the yarn is adapted to be drawn oii for the warping operation.

Fixed to the upper end of the creel frame,- one for each side thereof and exactly similar in form isa guide bracket 5 having mounted thereon a 30 guide rail 6 and a yarn separating reed l. The guide rail 6 is preferably in the form of a glass rod. for smoothly guiding the yarns thereover and the reed 1 preferably has glass dents 8 between whieh the yarns pass for being separated 35 on their course to the warper. Also fixed to the top of the creel frame is a double ended hanger 9 having depending supporting portions l0 and I l overhanging and above each of said creel frame sides. The supporting portions [0 and II each 40 have hook elements [2, l3, M, and I5 for a purpose to be later described. Angle brackets l6 and [1' are also formed-in said hanger for a purpose later described.-

As shown in I yarns are being guided from 4.5 the spools at the front side of the creel over the guide rail 6 through separating reed l and down to a block reed [8 which is mounted-at the rear of the reed carriage W of the warping machine. As shownin Fig. 3 this machine comprises the usual 50 warping reel or mill 2!), and reed carriage l 9 having a mounting. 21 for the condensing reed 22 and" a mounting 23' for the block reed l8. As shown in Fig. 9 a transverse support 24/ is provided on the reed carriage, said support preferably comprising two arms each of which is pivoted to the reed carriage and adapted to extend transversely thereof in line for supporting the reed stowing frame during the assembly of the reeds therewith as hereafter described. When not in use said arms of the support 24 may be mountable from their respective mountings 23. h and 2|. These two reeds are what I term herein" as a set of reeds, and I have providedfsaid set.

in duplicate for use in combination with this apparatus. V on the reed carriage in Fig.3.; The other set of reeds of exactly similar form is indicated as being contained in its stowing frame and rolled uptherewith in yarn remnants for temporary stowage on hooks l4 and I5 of the hanger'por- ;tion, ll.- There is a similarystowage; frame for each set of reeds and the details of one ;of said frames are shown in Figs. 4, 5,;and 6. The stowing frame preferably comprises; two long bars 25 andv 25 f equal length and adapted to be held together-upon theinterposed reeds by hooked springs 30 and 3|. These bars have a. length approximately equalto the width of .the' creel frame or the sheet of yarns led therefrom and only the end portions of the bars are adapted to rest inthe hooks I2, l3, l4, and I of-the hangers l0 and II. The upper bar and the lower bar 25 each has formed therein a long slot 21 for receiving the block reed I 8 and a short slot or notch 28 to' receive the condensing reed 22. Inasmuch as the condensing reed 22 is shorter in height than block reed l8 an adapter 29 is fitted to the same as shown in Figs. 4 and 5 so that when laid against the block reed the entire assembly may be clamped snugly between the upper and lower bars 25 and 26 and held together by the detachable springs 30 and 3|. 7 The operation of the apparatus may be described as'follows, referring more particularly to views l0, ll, l2, and 13; Assuming that the yarn supply on the front side of the creel is nearly depleted and requires replenishing the warper is stopped and the ends are cut and tied together at a point between the condensing reed and the warper. The cut off yarn remnants extending back to the creel will be left reeded through the several reeds 22, I8, and I. The adapter 29 is fitted to the top of the condensing reed as shown in dotted lines (Fig. 3) and the block and condensing reeds are then dismounted from the reed carriage and are brought together in juxtaposition and assembled within the stowage frame comprising rods 25, 26 and springs 30, 3|. During this assembling operation the lower rod 26 is conveniently supported in the transverse arms 24 on the reed carriage as shown in dotted lines in Fig. 3 (see also Fig. 11) Thereupon the stowing frame and its embraced reeds are rolled up in the yarn remnants which extend back to the creel as shown in Fig. 12 and are finally hung on the forward portion I0 ofsaid hanger 9 as shown in Fig. 13. Whenthe reeds are thus in stowed position it is desirable to prevent the yarn ends extending therefrom down to the spools from slacking up. Therefore there is provided as shown on the rear side of' the creel in Fig. 1, a felt covered clamp bar 32 coextensive in length with the glass rail 6 and 'heldyieldingly against One set of reeds is shown as mounted the same with the clamped yarns therebetween.

An encircling rubber band or spring (not shown) will serve to hold the clamp bar 32 against the rail 6. There is a duplicate clamp bar for each side of the creel and the idle clamp bar 32' and idle stowage frame bars 25 and 26' may be supported in the bracket 5 of the hanger. It will be understood that during the beaming on operation which has just been completed from the yarns onthe front side of the creel, full spools have been mounted onjthe rear side of the creel and "their ends have been tied into'the yarn remnants which have been stowed in the reeds on the hang er portion ll. Therefore the creel is now in condition to be reversed and bring its former rear side to the front whereby its previously stowed reeds in the hanger portion H are unrolled and mounted on the reed carriage for active function. The new yarn ends are then tied to the warper and the warping proceeds.

It will be observed that in the use of this ap- -p aratus when changing from one-supply of spools to the other the necessity of re-reeding the yarn ends is avoided. It willalso be observed that the operator in replacing v depleted spools with full spools and-tying in the same is able to work at the rear sideof the creel entirely away from .yarns running to the warp and therefore can accomplish these operations while the warp is being beamed. Furthermore after each beaming on operation when the reeds and yarn remnants are being stowed away preparatory to a reversal of" the creel, the warper may be operated for beaming off to its section beam in the usual manner. These several features of operation made possible'by the use of my apparatus all contribute to a considerablesavin'g of time and cost of labor in the warping. j
